Abstract

Ovaj rad istražuje ključne aspekte satelitskih komunikacija, počevši od povijesnog pregleda satelita do detaljne analize načina rada, orbita, frekvencijskih područja te višestrukog pristupa u komunikaciji.
Uvodni dio pruža pregled osnovnih parametara kvalitete satelitskog signala, uključujući broj krivo prenesenih bitova, pogrešku modulacije, odnos signala i šuma, zalihnost koda te unaprijeđeno ispravljanje pogrešaka.
Nadalje, razmatra se proces kodiranja i dekodiranja unutar satelitskog komunikacijskog sustava, uz primjere kodiranja i dekodiranja istih, pomoću Golay koda, Reed-Solomon koda te konvolucijskih kodova. Kroz razmatranje zaštitnih kodova poput cikličkih, BCH i konvolucijskih kodova, naglašava se važnost zaštite podataka u satelitskim komunikacijama.
Na kraju je prikazana praktična primjena u MATLAB-u, kodiranja DVB-S2 tehnologiji s LDPC i BCH kodovima.

Abstract (english)

This paper explores key aspects of satellite communications, ranging from a historical overview of satellites to a detailed analysis of their operation, orbits, frequency ranges, and multiple access in communication.
The introductory section provides an overview of basic parameters for satellite signal quality, including bit error rate, modulation error ratio, signal-to-noise ratio, code redundancy, and forward error correction.
Furthermore, the paper examines the process of encoding and decoding within satellite communication systems, with examples of encoding and decoding using Golay codes, Reed-Solomon codes, and convolutional codes. Through the consideration of protective codes such as cyclic, BCH, and convolutional codes, the importance of data protection in satellite communications is emphasized.
Lastly, practical application in MATLAB is demonstrated, focusing on encoding in DVB-S2 technology with LDPC and BCH codes.
